FASTENING MEANS.

Specification of Letters Patent.

Patented Oct. 15, 1918.

' Application filed May 1, 1918. Serial No. 231,820.

To all whom it may concern:

Be it known that 1, AUGUST H. RAINFT- LEN, a subject of the Emperor of Germany, (having taken out my first papers on the 6th day of April, 1917, in the process of becoming a naturalized citizen of the United States,) residing at Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fastening Means, of which the following is a specification.

This invention relates to fastening means or plates, and resides especially in the means for readily securing thereto or thereon the links of a chain or part or parts of some element or elements, and in means for preventing the escape of said links or other parts or part therefrom.

The invention is primarily intended by applicant for use in attaching anti-skidding chains or other devices, of the anchored type, to the spokes or felly of an automobile truck wheel. However, the invention may be used for a great variety of purposes.

The object of the present invention is to provide a stud, which may be integral with a plate, as shown, and at an angle to the face thereof. said stud being adapted to receive the terminal links of such a chain or a part or parts of some element or elements, and being provided with movable means to perm t the application or removal of such links or part or parts, but normallv guarding said stud against the escape therefrom of said links or part or parts.

Other objects are to so form the stud and guard or pin that, after assembly. they cannot be separated except by hard work with a file or chisel or similar tools, thus forming a self-contained unit. no part of which can, in use. become separated and lost.

In the accompanying drawings:

Figure 1 represents a perspective view of a segment of a wheel with a felly plate embodying my invention applied thereto;

Fig. 2, a perspective view of the felly plate with the ends of a chain, broken away, fastened thereto;

Fig. 3, a rear elevation of said plate;

Fig. i, a side elevation of said plate,

partly in section, with a link indicated in dotted lines in position of application or removal; and

Fig. 5, a perspective view of a modified form in which a spoke clamp is substituted for the felly plate.

Referring now in detail to the drawings, I indicates the solid tire, K the rim, H the felly. and G the spokes of the wheel.

The felly plate L is mounted on the inner peripheral face of the felly by means of a bolt 1, which may be formed integral with said plate, extending radially through said felly and receiving on its externally screwthreaded end a nut 2, which, on being tightened, holds the plate securely in place. The axial line of this bolt 1 will preferably correspond to the axial line of the stud 3 projecting from the other side of the plate.

This stud 3 is provided with a transverse internally screw-threaded hole which receives the externally screw-threaded stem of the bolt or pin 4, which serves as a guard for said stud, and which is provided at one end with an enlarged shoulder 5, which may be formed integral with said pin and is too large to pass through the hole in stud 3, as

.shown best in Fig. 4.

The other end is shouldered at 6 and provided with an angular extension 7, which receives the thumb-piece 8 for convenience in operation and also to provide this end with an enlargement which cannot pass through said hole. A split lock washer 9 is,

preferably, mounted on said pin between the piece 8 and the adjacent wall of said stud 3. to engage said wall and the adjacent face of said thumb-piece when the parts are in normal position and thus prevent movement of said pin 4 by vibration andthe like.

To assemble, the pin 4 is screwed into the 4 hole in stud 3, angular extension 7 first, until the shoulder 5 engages the side of stud 3 and the extension 7 protrudes beyond the other side thereof. The lock-Washer 9 is then passed over said extension 7 and onto the threaded part of the pin or guard 4 and the thumb-piece 8, having a hole corresponding in shape and size to the extension 7, is slipped over said extension, the end of which is then upset or riveted over, as shown in Fig. l, preventing the separation of the above mentioned parts. I

In operation, to apply a link, the guard at is screwed out until it takes the position shown in Fig. 4, the link is slipped over the thumb-piece 8, along the guard or pin l until it engages the side of the stud 3',- when said link is to be turned at an angle and passed over the top of said stud Sand the shoulder 5, as indicated in dotted lines in Fig; 4; The pin orguard 4 is their to be screwed in through stud 3 until further movement is prevented by the lock-washer engaging the opposing faces ofvthe stud 3 and; piece 8, its normal position.

This piece 8 is provided with wings or arms which are of suchsize and project at suchan angleit-o the stud 3 that the said links cannot be slipped over them by turningsaidlinks into a position at right angles to the dotted line position illustrated in Fig. 4:, in; fact piece: 8 will prevent said links from assuming such a position, and the pin l extending on the other side of the stud 3 will prevent said links from assuming the position illustrated in dotted lines in Fig. l so long as said pin or guard L is in normal position. Thus said links will be guarded against escape from said lug 8 when said pin or guards is in normal position, and in practically all other positions of the pin except thatillustrated in Fig. 4.

In the modificationshown in Fig. 5, a spokeirlamp, comprising plates A and B provided v with perforate d'end flanges G for the reception of bo'ltsD onwhich nuts E are screwed to draw the plates together on some: intervening object and provided with a rubber treated textile fabric lining ora rubber lining F, is utilized inplaceof the felly plate L of the preferred form, the stud 3. being mounted on the plate A of the modified form, Otherwise, the two forms are alike in all respects p In the use primarily intended the crosschain will have itstermin'al links N untwis'ted'to facilitate the application orvremovalto or from said stud of said terminal links a s H Having thus described my invention what I claimas' new and desire to secure by Lettersrliatent is: v a A l. A: stud adapted to receive detachably an element, in combination with-,m-eans nrovable transversely through said stud, said meansbe'ing so form-ed as to be. inseparable fr'ornsa-id stud and adapted, in nonnalpo' sition, to guard said stud against theescape therefrom 'of an endless article, said means being movable into a position allowing the application to, or removal from, said stud of said element.

2. A plate and a stud fixedly located on said plate, in combination. with means movable transversely of said stud and having screw-thread engagement with said plate,

stud provided with enlarged permanent parts whicln-because of their size, cannot pass through said studs, said means, in normal position, servingtox guard said stud against the escape therefrom of an element.

4. A plateandLa stud. fixedly located on said plate, in combination with a: screwthreaded guard movable transversely through said stud, having a shoulder on. one end too large to pass through said stud and a thumb-piece on the other} end, portion on the other side of aid stud, which thumbpiece is permanent y fixed to said guard and too large to pass through said stud, and a lock-washer: mounted n saidivluard between said tlru'rnb piece and the ad] acme fade of said. stud to lock said guard in norii'ial po- Saran. l 7 ,7 j a 5.
